CONTROL PANEL.

Application led .Tune 18, 1927. Serial No. 199,752.

This invention relates to new and useful improvements in .cont-rol panels and more particularly relates to such panels of the type adapted for use to control the li hting in theatres, auditoriums, or other budings where numerous lights are used which are frequently turned on and off to obtain different lighting effects.

An object of this invention is to provide a sectional control panel com rising a frame having a plurality of small sections demountably secured thereto and each having a plurality of selector switches mounted therein, and, whereby each such switch section may be removed as a unit from the panel for repairs or other urposes, and without the necessity of having to disconnect a plurality of wires or conductors. ,y A further object is to provide a control panel of comparatively small size, particularly adapted for use in theatres and similar places to control the turning on and ofi' of the stage and house lights, and all of the usual selector switches and operating or scene switch levers being incorporated in this one panel, whereby the operator ma control, at will and from one place, all of the lights on the stage and in the auditorium.

A further object is to provide a control panel comprising a plurality of sections, each having a series of selector switches mounted therein and operable in connection with a main operating switch to selectively turn on and olf certain groups of lights, and the electrical connection between the selector switches and the live bus bar, back of the panel, being made at the point of pre-setting of the selector switches. A further object is to provide a control panel having a plurality of selector switch sections, preferably mounted in superposed relation and tlie selector switches of each section, each having a stationary contact adapted to be engaged by a movable bus bar,

electrically associated with a source of electricalenergy and operable by a switch lever conveniently positioned on the' front ofthe panel, said switch levers controlling the openin and closing of the lighting circuits,

depen ent upon the pre-setting of the selecf' tor switches in each section.

Other objects of the invention are, to provide such a panel comprising a plurality of-A y lpart of this specication;

selector switches and scene or operating Switch levers pperatively connected together *it to the contacter by means of bus bars; to ,provide such a panel requiring comparatively few wires to electrically connect together the numerous switches mounted thereon; the construction of the selector switch sections and associated parts, which is such as to permit all currentcarrying parts back of the panel tol bey connected with the neutral wire' of the power line, whereby danger from short circuits, fires, and shocks to operators, is reduced to a minimum; to provide such a panel having all pilot switches,`master switches, light control'switches, etc.; incorporated in one small panel whereby all control and pilot light wires may be removed from the usual dimmer bank; tol provide such a panel requiring a minimum number of vwires for connecting panel whichvusually is located remote, therefrom, thus greatly re- Y ducing installation costs; the sectional construction of the control panel which permits adding more circuits to the panel when desired, at a. minimum expense; the general construction of the -demountable selector switch sections; and, in the provision of an extended kcontrol, whereby any desired setting of the selector switches may, if desired, be controlled at a point remote from the control panel.

The particular object of the invention therefore, is to provide an improved control panel, particularly adapted for use in theaplaces to control the turning tres and similar on and oil of the lights to yobtain certain lighting eiects,-which is so constructedand designed that all of the necessary switches are incorporated upon one small panel, whereby the turning on and off of the lights may be controlled from one point withfmore flexibility and more possible control combinations.-l v i Other objects of theginvention will appear from the following description and accompanying drawings and will befpointed out in the annexed claims.

In the accompanying drawings, there has beeny disclosed a struct-ure designed to carry out the variousrobjects of the invention, but it is` to be-understood that the invention is not confined tothe exact features shown, as various changes may be made within the scopeof thefclaims which follow.

The novel control panel featured in this invention comprises side frame members 11 suitably secured together by means of a plurality of panel sections, shown in Figure 1. As shown in this figure, the front face or side of the panel consists of a plurality of relatively small sections mounted in superposed relation and secured to the frame members 11 by means of suitable Screws 12. The section 13 at the top of the panel provides a support for a plurality of main operating switches 14, 15, 16, and 17, commonly known, respectively, as the white master switch, the red master switch, blue master switch and stage master switch. The purpose of these switches will subsequently be described. The bottom of the panel consists of asect'ion 18 having a transfer switch V19 mounted therein and also a pilot light switch 21. -The transfer switch 19 provides means for transferring the control from the stage master switch 17 to an extended control, usually consisting of a flexible extension cord having a switch provided at. one end thereof and having a plug at its other end. This extended control will subsequently be described. A rece tacle 22 is also provided in the section 18 a apted to receive the plug of the extended control.

A plurality of relatively smaller panel sections, A, B, C, D, E, and F are provided at intervals on the panel' between relatively larger sections 29 and 31.- The sections B to F, inclusively, are each provided with a plurality of selector switches 32, 33, 34, 35, 36, and also a switch 37, commonly known as a positive switch.

These selector switch sections are demountably and interchangeably secured t the panel. The blank section A, shown i Figure 1, is inserted for the purpose of providing means whereby the number of concontrolled trol circuits associatedwith the panel may be increased, if desired. This can readily be accomplished bysimply removing the blank section Aand substituting therefor a section having the desired switches mounted therein. A panel section 38, preferably of a size equal to the selector switch sections is interposed at any convenient point and has mounted therein a switch 39 adapted to control an auxiliary lighting circuit which may be independently of the lighting circuits connected with the other switches on the panel.

In Figure 1, there is showna control panel vsuch as might be used in a theatre or smula-r building for controlling a plurality of lighting` circuits. The upper portions of this panel is adapted to control all of the white lights of a given building, the intermediate portion, all of the red lights and the lower portion, the blue lights. The usual master switches are provided at the top of the panel. The white master switch 14 is electrically associated with all of the lighting circuits controlled by the upper group of selector switches; the red master switch 15 is similarly associated with the intermediate groups of selector switches, and the blue master switch 16 is electrically associated with the lower group of selector switches. The stage -master switch 17 is electrically associated with all of the lighting circuits through the color master switches 14, 15, and 16. Y

The operating mechanisms for the above described switches is shown in Figures 2, 3, 4, 5, 6, and 8. Figures 6 and 7 illustrate one of the selector switch sections removed from the panel. Each such section comprises a facing Aplate or panel portion 41 having terminal apertures 42 therein adapt-- ed to receive screws for demountably securing it to the side frame members 11, shown in dotted lines in Figure 6 and full lines in Figure 3. Each panel section or plate 41 has provided on its back side, longitudinally dlsposed spaced iianges 30, between which an elongated body 43, of insulating material, is seated and is suitably secured thereto by rivets 40. This elongated body has a plurality of stationary contacts 44 mounted thereon, as shown in Figures 5 and 6. Each contact 44 is secured to an apertured plate 45 and adapted to be seated against' one side of thebody 43 to provide means for securing the contact 44 thereto. Rivets 46 secure the plate 45 to the body 43. A connector. or bus bar 47 is secured to the opposite side of the body 43 and is secured thereto by the rivets 46. Each plate 45 has a contact seat 48. These contact seats are aligned with similar seats 49 provided in the connector bar 47. Each pair of contact seats or faces 48 and 49 are adapted to be electrically connected by a circuitioo y com-mon to all of the switches t lug 24 adapt-ed closing member 51, operatively associated with a. switch 52, shown in Figures 3, 6, and 8. Each switch 52 and its supplementary circuit-closing member 51 functions as a snap switch, and is adapted to close a circuit between one of the contact members 44 and the connector bar 47, which, it will be noted, is 52. A spring yretains the vmember 51 in its adjusted positions. Each switch 52 is mounted in a recess provided in the body 43.

Brackets 53 and 54 are secured respectively to the relatively larger panel sections 2S) and 31. Rock shafts 55 and 56 are-mounted respectively in the brackets 53 and 54. A plurality ot' contacts bars 57 are movably connected with the shafts 55 and 56 by means of arms 58 and 60, each having one end pivotally connected with a small bracket "59, provided at each end of the contactcarrying bar 57, as shown in Figures 4 and 5. Tension springs 61, each having one end secured their other ends connected to the rook shaft 55 by means of insulating members 63, mounted upon the shaft 55 as shown in Figures 4 and 5, are provided to constantlyV tend to move the contact bars 57 into circuit-open- -mg position, as shown in Figure 5. A plurality of Hexible contacts 64 are secured to each contact bar 57 and are adapted to be moved into and out of electrical connection with the stationary contacts 44.

A contact member 23 is secured to one end of the insulating body 43 and has a to have a. wire connected therewith, as will subsequently be described. This contact member has a contact face 25 adapted to be engaged by the circuit-closin member 51 of the posit-ive switch 37 to electrically connect the member 23 with the connector bar 47, which also is provided with a contact face 20 engageable by the member 51 as shown in Figure 3. A bracket 26 is also secured to the insulating body 43 and has a contactface face `28, provided upon the member 23. These faces are adapted to be engaged by the circuit-closing member 51 to close a circuit between the member 23 and bracket 26. The brackets 26 are electrically connected together by a. bus bar 10, having means for h connecting it to the power line as will subsequently be described.

Means are provided for actuating the contact bars 57 and switch handles 65, pivotally mounted upon the panelv sections 31, by means of pivots 66. I'Each switch handle has an extension 67 to which one end of a link 68 is connected, the other end of-which is pivotally connected to the opposite end of the arm 60, as shown in Figures 4 and 5. In Figure 5, the switch contacts 64 are shown intheir circuit-opening positions, while in Figure 4,

to a. pivot pin 62, and having 44 27 aligned with a similar i;

consists of a plurality of f the contacts 64 of one of the bars 57 are shown moved into circuit-closing position or electrical connection with the stationary contacts 44, provided on each selector switch section. The construction and general arrangement of the extensions 67 of the switch handles is such that when each switch handle 65 is moved to the lower or circuitclosing position shown in Figure 4, the axis of the pivot `vill pass over the center, thereby locking the links 58 and 60 against oscillatory movement, with the result that the flexible contacts 64 will be held in electrical connection with the stationary contacts 44, against the tension of the spring 61. As soon as the switch lever 65 is moved upwardly, the tension spring 6l will automatically return the contact bar 57 to its normal inoperative position, as shown in Fi re 5. 1n this ligure, it will be noted that all of the flexible contacts 64 have been moved out of electrical connection with the contacts The novel control panel featured in this invention is particularly adapted for use as a remote control for a plurality of relayactuated circuit-closing switches which function to directly open and close a plurality of lighting circuits and which switches are usually located remote from the control panel.

Figure 9 illustrates a typical installation of the novel control panel as used in connection with the various lighting circuits employed in a theatre, or similar building. The relay-actuated switches B', C', D', E, and F are of ordinary construction, and each comprises an armature 7l operable by g a relay coil 72 having one end connected by a wire 73 to a. conductor 74, which is electrically associated with the conductor 75 of the power line, as shown. The power line comprises the usual positive wires 75 and 76 and the neutral wire 77. Each relay coil 72 is connected with the supply wire 74 and hus has one end constantly connected with the power line. The other sides of the relay coils are electrically connected respectively by the wires 78, 19, 81, 82, and 83, to their respective terminals 84 of the positive switches 37, as shown at the upperright and portion of Figure 9. lln order to simplify the wiring` diagram, the wires 78, 79, 81, 82, and 83 are shown connected directly to the positive switches 37, which switches unction to electrically connect these wires with their complementary contact face 20 of the connector bars 47, or, with the contact faces 27 of the brackets 26. The bus bar 10,. connecting together the brackets 26, has a wire 85 connected thereto at 80, end of which is connected to the neutral wire 77 of the power line.

The circuit-closing switches B, and F are electrically associated with wires such as gravity or by springs.

y preferably 71 will be attracted thereby 86 and 87 connected respectively by wires 88 and 89, with the wires 75 and 77 of the power line as shown.

The purpose of the selector switches 32, 33, 34, 35 and 36, and the main operating or scene switches 65, mounted upon the control panel as shown in Figure 1, is to' provide means for selectively energizing the relays 72 to cause therelay switches B', C', D', E', and F to be moved into closing position, these switches normally being retained in circuit-openingposition by suitable means,

When one of the relay coils 72 1s energized, its armature and will move the switch elements into circuit-closing position to cause the lighting circuits to function. The selector switches 32, 33, 34, 35, and 36 mounted in the panel sections B. C, D, E, and F, provide means for selectively presetting or conditioning the relay circuits so that when the scene switch levers "are actuated, those relay circuits whose selector switches have been pre-set, and are associated with the particular scene lever which has been actuated, will cause the relays associated therewith to be energized to close the lighting switch, after which the lighting circuit associated therewith, will function.

The bus bars 57, operated by the scene switch lever 65 are each electrically connected with a feed wire 91 by means of, a connection 92. One end of the feed wire 91 is electrically connected with a post 93 adapted to be engaged by a movable contact 94, connected with an armature 95, which is operable by means of a relay coil 96 to move the contact 94 into circuit-closing positions. A wire 97 connects the movable contact 94 with the neutral wire 77 of the power line. One side of the relay coil 96 is connected with the wire 74 and the other side thereof is connected by a wire 98 to a three-way switch 99, commonly known as the white master switch. This switch controls the opening and closing of all of the white lighting circuits which have been pre-set by means of the selector switches and the scene switches 65. The white master switch 99 comprises contacts 101 and .102 to which the wire 98 is connected, and also contact posts 103 and 104, to which are connected respectively the wires 105 and 106'. The wire 105 has its otherr end connected to a contact'post 107 adapted 'to be engaged by a movable contact 108. which also neutral wire The movable Acontacts 94 and 108 are normally held in circuit-opening positions, by suitable tension means, not shown. The wire 106 of the white master switch connects the post 104 with the wire 85, leading to the neutral wire 77 of the power.` line. The movable contact 108 has is electrically connected with ther 77 by means of the wire 97.'

an armature 109 adapted to be operated by a relay coil 111 to move the contact 108 into electrical connection with the contact 107. This relay coil similarly has one end connected to the Wire 74 and its other end is connected by a wire 112 to the contact posts 113 and 114 of a similar three-way switch, known as the stage master switch. The stage master switch is similarly provided with contacts 115 and 116, the former being connected to the transfer switch 19 and the latter to a wire 118, .leading from the neutral wire 77 of the power line, to the receptacle 22 mounted in thevlower portion of the control panel as shown in Figurevl. The transfer switch 19 is connected by wires 119 and' 121 to the other contacts provided in the receptacle 22, as shown in Figure 9. An extended control switch 122 having .contacts 123, 124, 125, and 126 is provided for controlling from a remote point, the lighting circuits which' have been pre-set. This extended control switch is connected by wires 127, 128 and 129,' to a plug 131 adapted to be electrically connected with the receptacle 22 in the usual manner. The wires 127 128, and 129 are tied or connected together to provide a flexible cord and may be of any suitable length required. By means of this extended control switch, all of the lighting circuits which have been pre-set by manipulation of the selector switches and scene switches upon Lthe control panel, may be controlled from a distant point. The sta-ge master switch is preferably mounted upon the panel, as shown at the upper right hand corner of Figure 1, and by the manipulation of this switch, all of the lighting' circuits having been pre-set by the selector and scene switches, may be turned on and of by the simple manipulation of this one switch.

In the wiring diagram, Figure 9, there is shown onlythe roup of selector switches and scene switcles controlling the white lights, while in Figure 1, three groups of selector switches lare shown, namely, those controlling the whitelights, those controlling the red lights and those controlling the blue lights. his is the usual and common arrangement of lights as used in theatres and buildings of that character. The wiring connections necessary to control the 'red and blue lights, of course, will be similarto those required to control the white lights,

2, section E, the"white border No. 3, and section F, the white pockets. The wiring diagram has been similarly marked. In Figure 9, all of the positive switches 37 are shown in their normal position, wherein it will be noted, that theyelectrically connect ,the connector bars 47 with their respective `relay circuit wires 78, 79, 81, 82, and 83. When the white master switch is in the fu v.line position shown in'Figure 9, and t-he positive switches 37 are in their full line position shown, manipulation of the scene switches 65 will have no effect upon the lighting circuits controlled by the relayactuated switches, B', C', D', E', and F, for the reason that the movable contact 94 is in circuit-opening posit-ion. Therefore, before the scene switches 65 can function, the white master switch must be moved to the dotted line position shown wherein the relay coil 96 will be energized to pull the contact 94 into circuit-closing position with the contact 93. Such actuation of the white master switch will therefore cause all of the relay circuits which have been preset by their respective selector switches, to cause their respective lighting circuits to function, when the scene switches associated therewith are moved into circuit-closing position, as shown at the left hand side of Figure 9; In this figure, it will be noted that the selector switch 32 of section C, white borderNo. 1, has been moved into circuit-closing position, and also that the selector switches 32 of the sections E and F of the white border No. 3 and white pockets respectively,`have been moved into circuit-closing position. Thus, when the scene lever 65, associated therewith, is moved downwardly to the position shown, these groups of lights will be caused to function, as al result of the relay coils of the white border No. 1, White border No. 3 and the white pockets will be energized to close their respective switches C, E', and F.

Before the lighting circuits controlled by the relay-actuated switches B', C', D., E, and F can be controlled by the main operating or scene switches 65, the color master or white master switch 14 must be positioned as indicated by the dotted lines in Figure 9, thereby causing the relay coil 96 to be energized to move the contact 94 into circuit-closing position with t-he stationary contact 93. When the white master switch 14 is thus positioned, the lighting circuits associated wit-h the relay circuits which have been pre-set by the closing of their respective selector switches, may be controlled at will by the simple manipulation of the scene switches which, it will be noted, completes the closin of the relay circuits 78, 79, 81, 82, and 83, w ereby the relay coils 72 will beJenergized to close the relay-actuated switches B', C', D", E', and F. When the have been pre-set, as shown at the left hand side of Figure 9, and the main operating or scene switch associated therewith has been moved into circuit-closing position, all of the lightin circuits associated with the selector swities which have been pre-set, may be caused to lation of the white master switch 14, by moving the member 99 from the full to the dotted line position shown in Figure 9. Thus, several groups of lighting circuits may be conditioned by the manipulation of the selector switches of a given color group, and the turning on and off of the lighting circuits associated therewith may thereafter be controlled entirely by the master switch 14.

The stage master switch 17 provides means whereby all of the lighting circuits controlled by each group of selector switches and scene switches may be controlled simultaneously by the simple manipulation of this one switch. lrVhen the stage master switch is used as a single control for all of the lighting circuits, all of the color master switches 14, 15, and 16 must be positioned as shown in full lines in Figure 9. When thus positioned and the stage master switch 17 is moved from the full to the dotted line position shown in Figure 9, the movable contact 108 will be moved into electrical connection with the post 107, thereby completing a circuit through the relay coil 96 by means of the wire 105, contact member 99, post 102, wire 98, coil 96, wire 74, and back to the conductor of the power line. Such energizing of the relay coil 96 will therefore cause all the lighting circuits, whose relay coils have been pre-set by their respective selector switches, to be turned on when the stage master switch 17 is positioned as shown in dotted lines in Figure 9, and which lighting circuits will be turned off when the stage master is positioned as shown in full lines in Figure 9.

The positive switches 37 provide means whereby each group of lights of a given color may be turned off and on independently of the selector switches or main operatinnr switches 65. It will readily be noted by re erence to Figure 9, that when one of the switch members 37 is moved into electrical connection with its complementary contact post 27 as shown in dotted lines at the upper right hand portion of Figure 9, the relay circuit 7 8 will be closed, thereby causing the energization of the relay coil 72 of the switch B', which therefore will cause this function by the simple manipu- Y a side of the supply switch B position to ,cause the white foots to be turned on. These switches 37 therefore provide means whereby each lighting circuit may be controlled independently of the selector switches `and operating switches 65, and also independently of each other. l

The novel control panel featured in this invention is so arranged that all contacts and connections back of the panel may be connected with the neutral wire 77 power line, whereby danger from short circuits, fires and shocks to operators are reduced to a minimum. Also, by mounting a plurality of selector switches in each panel section, A, B, C, D, E, and F, and providing a common bus bar for connecting together such switches, the amount of wiring required to electrically connect the selector switches with their respective lighting circuits is reduced to a minimum.

Figure 10 illustrates a modied form wherein the main operating or scene levers 65 have been dispensed with and, in place thereof, a pair of solenoid coils 135 and 136 are provided for electrically operating the contactor bars 57. An armature 137 is movably mounted within the coils 135 and 136 and has a connection with the pivot 80, as shown. A switch 138 provides means for controlling the energization Iof the coils 135 and 136. This switch has a wire 139 connecting it to one side of an electric supply circuit. A wire 141 leads from the other circuit to one end of each coil 135 and 136. The coil 135 has a wire 142 connecting it to a contact post 143 and the coil 136 similarly has a wire 144 connecting it to a contact post 145 of the switch 138. When the switch 138 is moved into electrical connection with the contact 145, the coil 136 will be energized to attract the armature 137,. which will therefore be drawn into the coils with the resultant actuation of the arms 58 and 60 to move the bar 57 into circuit-opening position. When the switch 138 is moved into electrical connection with the post`133, the upper coil 135 will be energized to return the armature to the full line position shown in Figure 10, thereby causing the bar 57 to be moved into circuit-closing position.

In the drawings, I have Shown the usual pilot or signal lights, such as are commonly provided in apparatus of this type for indicating'to the operator the condition of the lighting-circuits, but all pilot light wiring has been omitted 'in order to simplify thel drawings.
